tyre burst

hi,
In my project i need tyre burst effect,for this iam planing to delete the tyre and adding it by reducing the tyre radius.Iam able to delete the tyre,but when iam adding it iam getting the error.

Any one in the forum give me some idea how can achieve the tyre burst,or give me some other idea to get the effect.
thanks in advance,
regards,
prathap

I don't follow, what do you mean "you get the error"? And, I guess you could animate the tire bursting?
